This is a sketch I did of Mr. Rivets while I was working on the first book, The League of Seven, so the illustrator, Brett Helquist, would have some idea of how I saw Mr. Rivets. His take on Mr. Rivets is very different–and very cool! Just because I see Mr. Rivets a certain way in my head doesn’t mean you or Brett can’t see him differently. That’s part of what’s so cool about books as opposed to movies–everybody can imagine the characters and world however they want!
